Fourth, the word is divided into two general Que, the longest sequence莺啼〔〕 only 240 characters and the capacity of music to enrich the performance of much more, it can be a combination of a number of songs, a palace belonging to the same tune song, may be a rhyme in the end, this result is not only more in harmony in music, but also in写景, flakes, lyric, narrative are less restrictive.

第四，词一般分为两阙，最长的〔莺啼序〕也只是二百四十字而曲的表现能力要丰富得多，它可以把若干曲组合为一套，一套曲属于同一宫调，可一韵到底，这样做的结果是，不单在音律上更为和谐，而且在写景、状物、抒情、叙事上都较少限制。

Each time after putting to (the instrument with the set of Yamshidi-Nadel provided by Kypho of America for injection of bone cement into the vertebrae; each putting could contain about 1.5 mL bone cement) inject bone cement into the vertebrae, the pressure P was not very high, with 500 kPa bar below for majority and the effect caused showed a significant statistical difference (P.01). Whereas, the pressure within the area of the vertebral P value was not high either, the majority was 10.00 Unit lower, which also led to the effects of significant difference (P.01). Both two states showed partial distribution. After making the statistical analysis to the casual two puttings between the first, second, third and fourth putting of each vertebrae, there existed the general differences. The differences were also found between other puttings (a.0083) on the statistics basis apart from between the first and second and between the third and fourth.

结果 每个椎体的椎体成形术均达到临床评价要求，每次推杆（美国Kypho公司提供标准椎体成形术中Yamshi-Nadel套系中推注骨水泥入椎体的器具，每具推杆可容纳骨水泥约1.5mL）推注骨水泥入椎体时所产生的椎体内的压力P不是很高，多数在0.50 bar以下，其所导致的效应具有显著的统计学差异(P.01)，而每次推杆推注骨水泥入椎体时的椎体内压力面积值P也不是很高，多数在10.00 Unit以下，其所导致的效应具有显著的统计学差异(P.01)，两者均呈偏态分布；而且，对每例椎体的第一、二、三、四杆之间两两予以统计学上的分析，在总体存在差异有统计学意义的基础上还发现除第一和二杆、第三和四杆之间外，其他各杆之间存在着差异(a.0083)。
